Cataclysm Beta - Build 12759
A new build is being deployed on beta realms, just like any beta build, it will be painful, a lot of stuff will break, and I have no idea if I'll be able to give you all the content on the first day.

On the upside, Thrall is getting a new model. Stay tuned for changes!

Nemesis in Hyjal looks really nice too.

Guild Vendor Rewards
The Guild Vendor is here, a lot of items are placeholders but it should give you a pretty good idea of what it will offer.

And if you're wondering.

Loading Screens
Loading screens for each continent have been updated.

Spellbook - Mounts and Companion Pets
The Mounts & Companion Pets are now in the spellbook with a brand new interface.

Tol Barad
Tol Barad is open for testing, this is a new outdoor/PvP zone with a daily quest area for the faction controlling it. More on that later.

310% Speed Flying Mount
The new 310% Speed Flying Mount skill costs 5000 gold to train. People who already own a 310% flying mount get it for free.

Relic Slots Items
All classes items in the relic slot now have stats.

Masteries and Armor Specialization
Masteries and Armor Specializations are now available for testing.

Video Settings
The Video Settings menu has been expanded, looks like we'll be able to tweak more things in Cataclysm.

Creature Damage Output Changes

Creature damage output has been increased from roughly level 65 and up. These increases scale upward with level. Creatures in exterior zones at level 80 now have 2.5 times the damage output they did previously in beta, 3.2 times at level 81, and 4 times at level 82 and up.

We’d like to get your feedback about how combat feels with creatures in level 80-85 exterior zones, including spawn rates and numbers of creatures in specific locations in each zone. Please let us know if this feels adequately challenging, or if there is a little too much face rocking going on.
